Dr. Sally Weinstein was interviewed on NBC5 Evening News, along with Dr. Mark Rasenick, to discuss the impact of Dr. Rasenick’s breakthrough depression research in the field

New research shows scientists have found a specific protein in both our brains and our blood that could be a hallmark for depression.

We have identified a biomarker that's very simple to measure," said Mark Rasenick, a University of Illinois Chicago distinguished professor of physiology and biophysics and psychiatry and a neuroscientist with the Jesse Brown VA Medical Center.

To have a blood test just really underscores and validates that depression has a biological origin and is a medical condition, no different from something like asthma or for diabetes," said Dr. Weinstein, who is also the Associate Director for the University of Illinois Center on Depression and Resilience.
